Okay, first thing is you want to have x and y all alone. So you need to solve the equations.
Equation 1:
5x+4y=12 (you want to subtract 5x on both sides to get y on one side and x on the other)
5x+4y=12
<u>-5x -5x
</u><u> 4y=12-5x</u> (Now if you want x and y alone you want to divide 4 on both sides)
4
y=3-1.25x Now that's you equation
Equation 2: (Basically the same steps for the 1st equation)
3x-3y=18 (Subtract 3x on both sides)
<u>-3x -3x </u><u>
</u><u>-3y=18-3x </u> (Now you divided by -3 on both sides)
-3
y=-6+x (you might notice why is there only 1 x, well because -3 divided by -3 is going to be a positive 1. You can either put a "x" or a 1x, doesn't really matter).
now since you have the two equations simplified you want to solve by doing multi-step.
3-1.25x=-6+x (Now you want to add 1.25x so you can get rid of the negative x)
<u> +1.25x +1.25x
</u> 3= -6+2.25 (Remember x alone is like 1, so it's like 1+1.25, next you want to add 6 on both sides. So you have a number and a variable all alone).
3=-6+2.25x
<u>+6 +6
</u><u>9 </u><u>= </u><u>2.25x</u> (Next you divided 2.25 on both sides)
2.25 2.25
Answer:
x =4
If your not sure, you can plug in or replace x with 4. :D

Answer:
Part 1 - Local Package Store 0.75 × 10 = $7.50 + $3.30 = $10.80
Nationally-Owned Package Store 0.95 × 10 = $9.50 + $3.30 = $12.80
Part 2 - Local Package Store #1 0.75 × 15 = $11.25 + $3.30 = $14.55
Nationally-Owned Package Store #2 0.95 × 15 = $14.25 + $3.30 = $17.55
Part 3 - Local Package Store #1 0.75×17 = $12.75 + $3.30 = $16.05
Nationally-Owned Package Store #2 0.95×17 = $16.15 + $3.30 = $19.45
Part 4 - 1. The Local Package Store was Cheaper for all three packages than the Nationally-Owned Package Store.
2. The Local Package Store is cheaper for the 1 pound 1 ounce package than the Nationally-Owned Package Store.
Answer:
2nd one.
Step-by-step explanation:
she starts with 45 books, so it's the "0th" month. then after, 1 = first month, so 50. 2= 2nd month, 55, and so on and so forth.
